Refresh CORD-19 annotations with latest scibite annotations

Note they use PRO as the vocabulary. We can ingest the PRO file... but it may be easier just to add the PRO xrefs into our curated gpi file

@cmungall @deepakunni3 does SciBite definitely use PRO as their vocabulary for SARS-CoV-2 genes? I can't confirm this - for example, I can't seem to find for example the PRO ID for Spike protein:

in the transformed data from SciBite version 1.5:

$ grep 000050269 data/transformed/SciBite-CORD-19/nodes.tsv  data/transformed/SciBite-CORD-19/edges.tsv
$
